There is a guy named Scott that is real good on boat motors that is real close to Lake Talquin. He is fair and reasonable. I have had to visit him 3-4 times over the years while fishing Talquin. I was thinking his business was called Scott's Speed Shop, but Google Maps says it is called Speed and Custom Marine. He is located on Old Federal Road. His phone number is 850-875-0381. Hope you get it going.
